AppIication filed March 14, 1916. Serial No. 84,079.

To all whom it may concern:

Be it known that I, DAVID G. CONN, a citizen of the United States, residing at Roseburg, in the county of Douglas and State of Oregon, have invented certain new and useful Improvements in Stanchions; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cattle stanchions and the primary object of the invention is to provide a. stanchion which may be set so that when the cow inserts its head through the stanchion, it will release the means for holding the stanchion open and allow the stan chion to automatically close.

Another object of this invention is to provide a stanchion as specified which includes a rigid member having one side thereof pivotally connected to the lower end of the main body of the stanchion, which pivoted member has a catch connected to its upper end to which catch a Weight is connected for automatically moving the pivoted side of the stanchion into a closed position and to provide means carried by the rigid body of the stanchion for locking said hinged side in a closed position or for holding it in an opened position prior to the insertion of a cows head into the stanchion.

A still further object of this invention is to provide a novel suspension structure for suspending the stanchion, which will hold the stanchion in its proper position for the cow to put its head into the stanchion.

With the foregoing and other objects in.

View this invention consists in such novel. features 01 construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying draw ings wherein like characters designate like and corresponding parts throughout the seve 'al views, and in which:

Figure 1 is a side elevation of the improved stanchion. 2 is an end elevation of the stanchion showing a part of the lower end of the stanchion broken away. Fig. 3 is a sectional view through the upper end of the stanchion. Fig. 4; is a. top plan view of the stanchion. Fig. 5 is a fragmentary side elevation of the stanchion illustrating the side opposite to the one illustrated in Fig. 1, Fig.

6 is av sectional view on the line 66 of Fig. 3, and Fig. 7 is a fragmentary sectional view through a part of the suspending structure. Fig. 8 is a detail sectional view through the upper end of the stanchion.

Referring more particularly to the drawings, l designates the main body of the stanchion, which comprises a vertical side 2 and upper and lower horizontally positioned sides 3 and at. The main body of the stanchion is preferably formed of pipe, and the vertical section 2 has substantially one-half of the pipe cut away as clearly shown in Figs. 1 and 2 of the drawings for decreasing the weight oil the stanchion.

The lower horizontal end 1 oi the body 1 of the stanchion has a bar 5 pivotally con nected thereto as is shown at (5, which bar 5 is bent intermediate its ends, as shown at 7 to provide an oiiiset portion 8, so that the distance between the facing sides of the vertical side 2 and the vertical side 5 may be altered as desired, by changing the position of the bar which forms the vertical side 5.

A rod 9 is connected to the upper end of the bar 5, and extends transversely thereto having an eye 10 formed upon its outer tree end, towhieh a cable or rope 11 is attached. The cable or rope 11 passes over a pulley 12. carried by the upper corner of the body 1 and it extends downwardly along the vertical side 2 of the stanchion body 1 and is connected to a. weight 13. T he weight 13 is guided in its vertical movement by straps 1 1 which are termed. upon the vertical side The bar 1 has :1 depending lug 15 formed thereon which is adapted for cooperation with a pivoted catch 16. The catch 16 is carried by a rod 17, which is rotatably journaled in the sides of the top horizontal section 3 ot the stanchion body 1. T he outer end of the rod 17 is bent upwardly and increased in size as shown at 18, for swinging the catch 16 out of an engaging position with respect to the lug 15 as will be hereinafter more fully described.

The horizontal section 8 has relative resilient plates 19 connected thereto which form guides for the movement of the upper end of the vertical bar 5. The vertically positioned bars 19 have their outer ends connected as is shown at 20, to form means for limiting the outward movement of the upper end of the pivoted side bar 5. The upper or horizontal resilient bar 19 has a catch 19 formed upon its upper end which engages the upper end of the side 5 of the stanchion for looking or holding the same in a closed position.

In the operation of the improved stanchion; when an animal is released from the stanchion the handle 18 is pushed back, andthis causes the member 16 to move upwardly, so that the pivoted side bar 5 cannot close because the member 16 will form an obstruction in the path of the upper end of the pivoted side bar, as clearly shown in Fig. 8 of the drawings. When an animal inserts its head into the stanchion, it will force the pivoted side 5 outwardly, and the latch 15 will engage the lug 21 formed upon the member 16, which will throw the lever 18 past a center and into the position illustrated in Fig. 3 of the drawings, moving the member 16 into a vertical. position, and thus allowing the weight 30 to draw the pivoted side 5 of the stanchion into a closed position where it will be held by the shaft 19.

A novel suspension structure generically indicated by the numeral 25 is provided. This structure includes a member 26 which has a head 27 formed upon its lower end. The head 27 has an upstanding shank 28 formed centrally thereon, the upper end of which is pivotally connected as is shown at 29 to links 30, which links are in turn pivotally connected to each other as shown at 31. The upper surface of the head 27 is cut at an angle as clearly shown at 32 in Figs. 1 and 7 of the drawings. 7 A collar 33 is slidably mounted upon the shank 28 of the member 26 and it has its lower end angled to conform to the angle or incline of the upper surface of the head 27. A bail member 34L is connected to the collar 33, and it is held in firm engagement with the upper horizontal side 3 of the stanchion body 1 by a bolt 35, which extends through the sides of the bail member 3 1. When the stanchion is hanging free, the angled sides or surfaces of the head 27 and the collar 33 are in abutting engagement with each other, which holds the stanchion in its proper position against turning movement, so that the cow can easily get her head through the stan chion. After the cows head is inserted through the stanchion, and should there be slack in the lower chain 36, which is connected to the lower horizontal bar 4: of the stanchion, the stanchion may be swung without bending the hanger structure 2 5 in at the inclined surfaces of the collar 33 and the head 27 will be moved out of engagement with each other and the collar will swing or rotate on the standard 28, thereby allowing free swinging movement of the stanchion. A pivoted link 30 permits of a swinging movement of the stanchion in a forward and rearward direction.

Copies of this patent may be obtained for From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved stanchion will be readily apparent to those skilled in the art to which this invention appertains, and while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scopeof what is claimed.

lVhat is claimed is 1. In a stanchion structure, the combination of a main body portion, one side of said stanchion being pivotally connected to said main body portion, a rod detachably COllnected to the upper end of said pivoted side, a cord connected to said rod, a weight connected to said cord for automatically moving said pivoted side into a closed position, a rod rotatably carried by said main bot v portion, a lug mounted upon said rod, a lug formed upon said first named rod and adapted for engagement with the lug carried by said rotatably mounted rod for holding said pivoted side in an opened position against the action of said weight.
